Jeremy was awesome, he had constant communication and made extra effort to get the prints right. One of my requests was something a bit too difficult to print, but he communicated that with me and still made it work. Jeremy even sent the "failures" as bonus with detailed labels on everything. The "failures" still fit and work fine, they're just a tad wonky looking but structurally sound... which is basically how I might describe myself so who am I to judge.
The plastic sliders on my beyerdynamic dt 770's broke and these were a perfect replacement. There was a bit of shrinkage, but still worked fine. I am overall satisfied with my purchase and the print quality.
Response: Hi Kevin,
Sorry to hear you weren't completely satisfied, usually the printer is pretty accurate on dimensions.
Please let me know how you determined there was shrinkage, and how it affected the function of your part, and I will be happy to ship a replacement if necessary.
